Yusei Fudo is the protagonist of Yu-Gi-Oh! 5D's. His first appearance was to deliver to his rival, Jack Atlas, the important message of "Card games on motorcycles!", starting what would eventually become a new Internet meme. In the "10th Anniversary Movie Abridged Trailer", he teamed up with Yugi Muto and Jaden Yuki to Duel against the antagonist, Paradox. In the legendary rap battle between Jaden and Yugi, he arrives to accidentally run Jaden over, shortly afterward, declaring his reason for arriving was "to play a card game". He later panickingly asks Yugi if he had run over Kuriboh prior to his arrival, by which Yugi casually insists that "it was only Jaden".
Yusei also appeared in the Yu-Gi-Oh 5Ds One Shot Parody Special, where he was shown to be very arrogant and selfish. He considered his Duel Runner as his girlfriend, and at one point considered making out with it. He, Jack and Crow were once in a punk rock band called "Team Satisfaction" with a guy named Kiryu. They wanted to have the gayest name of the century, but Coldplay was already taken. Unfortunately, the band split during their first live concert, due to Jack's screaming during the mic check, which caused the Zero Reverse. Also, due to his constant riding addiction on his motorcycle, he has a special medical condition where he has orgasms due to a different number of causes (excluding the sound of Akiza's voice).
In "Yu-Gi-Oh! Bonds Beyond Time Abridged", Yusei is also portrayed as somewhat misogynistic. He and Jack seem to hate Akiza (and possibly other girls in general) because they claim with no reason that "girls are smelly". When Akiza retorted logically that motorcycles are smelly, he sternly demanded that she leave his house.
He also shows extreme contempt towards Jaden (specifically his energetic cheerfulness), and tells him that he's going to "tear the happy from [his] soul", among other verbal potshots. On the other hand, he seems to have something of a sexual attraction towards Yami, though he quickly states "No homo" hiding the fact he comes from the far future, where omni-sexual attractions have long been legalized. He also shows a concern for the space-time continuum, trying his best to prevent the curious Jaden from accidentally destroying it by Jaden leaking spoilers to Yugi - something he ultimately fails at preventing.
Also in the BBT movie, Yusei is shown to have a habit of questioning "what is wrong" with Jaden's, Yugi's and Yuya's hair--noting their bizarreness, completely oblivious to the fact that his own hairstyle are just as bizarre and questionable especially with his yellow hair highlights. Yusei also delusionally believes that he has won every duel he takes part in, saying "I totally won that duel," even when there isn't a duel going on.
He is voiced by TheAzureCrow, whose most famous work is Gurren Lagann the Satire.
